ultra high-purity hydrogen gas generator / process / multi-use / onsite
Max.: 5,000,000 Pa (725.19 psi)
Min.: 500,000 Pa (72.52 psi)
Hydrogen electrolyte and oxygen electrolyte circulate separately, hydrogen electrolyte pumps into hydrogen cell directly and oxygen electrolyte
pumps into oxygen cell directly, and therefore gets higher purity of hydrogen and oxygen gas.

O2 capacity 1-250 Nm3/h
H2 purity % >99.9
O2 purity % >99.5
Power consumption (DC) < 4.5 kw.h/m3H2
Electrolyte 30% KOH
Work pressure 0.5-5.0MPa
Electrolysis Process Overview
Electrolysis is the passage of a direct electric current through an ionic substance that is either molten or
dissolved in a suitable solvent, resulting in chemical reactions at the electrodes and separation of materials.
The main components required to achieve electrolysis are :
An electrolyte : a substance containing free ions which are the carriers of electric current in the electrolyte.
If the ions are not mobile, as in a solid salt then electrolysis cannot occur.
A direct current (DC) supply : provides the energy necessary to create or discharge the ions in the electrolyte.
Electric current is carried by electrons in the external circuit.
Two electrodes : an electrical conductor which provides the physical interface between the electrical circuit providing the energy and the
electrolyte. Electrodes of metal, graphite and semiconductor material are widely used. Choice of suitable electrode depends on chemical
reactivity between the electrode and electrolyte and the cost of manufacture.
